1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundPancreatic cancer (PC) is characterized by profound immunosuppression and marked biological heterogeneity. Stromal tumor-infiltrating lymphocytes (TILs) reflect host antitumor immunity, whereas peroxiredoxin 4 (PRDX4) represents tumor redox adaptation. However, their combined prognostic value remains unclear.

methodsWe retrospectively analyzed 138 resected cases of PC. Stromal TIL density was assessed on hematoxylin-eosin (H&E) sections, and tumor PRDX4 expression was evaluated by immunohistochemistry. Both markers were dichotomized into high and low groups using ROC-derived thresholds. Patients were further classified into four integrated subgroups: TIL-high/PRDX4-low (TH-PL), TIL-high/PRDX4-high (TH-PH), TIL-low/PRDX4-low (TL-PL), and TIL-low/PRDX4-high (TL-PH). Associations with clinicopathological features and disease-specific survival (DSS) were analyzed.

resultsHigh TIL density was associated with less advanced pathological stage and significantly improved DSS, whereas high PRDX4 expression correlated with lymphovascular and perineural invasion as well as advanced stage. An inverse association between TILs and PRDX4 was observed. Integrated subgroup analysis revealed distinct prognostic patterns: the TL-PH subgroup showed the poorest DSS, whereas the TH-PL subgroup demonstrated the most favorable outcomes. In multivariable Cox models, the TL-PH subgroup remained an independent adverse prognostic factor for both 3- and 5-year DSS, while the TH-PL subgroup showed a protective effect, particularly at 3 years.

conclusionsStromal TILs and PRDX4 appear to capture complementary immune and redox features of PC. Their combined assessment may improve prognostic stratification and help to identify a potential redox-associated, immune-excluded subgroup with particularly poor outcomes.
